About the project:

Under pressure: Predictive modelling of battery ageing across the scales

Supervisor: Dr Lukasz Figiel, University of Warwick

Lithium-ion batteries are essential for electric vehicles and achieving net-zero targets, but they degrade over time, reducing performance and safety.

A key issue is gas generation, which causes internal pressure build-up and can lead to cell failure, but existing models struggle to capture this complex, multiscale phenomenon efficiently.

This project will develop a novel, physics-informed surrogate model using Bayesian machine learning to predict gas generation and pressure evolution.

Our approach will combine physical insight with data-driven techniques and uncertainty quantification, offering fast, reliable predictions and contributing to safer, longer-lasting batteries.
